I've seen such possibility in game (Menu - Injuries) but couldn't figure out how to use it.Any advice\suggestion what to do to put person not on IR-endning season list - but to IR designated to return?Thanks!

I thought the only way to prevent someone counting against your roster was to put them on IR. Doing that means they can't play for the rest of the season. If they are simply injured and not on IR, then they count against your 53-man roster. I didn't think there was any middle ground.
